Organized Christianity has probably done more to retard the ideals that were its founders' than any other agency in the world.

Le Gallienne contrasts the ethical and spiritual ideals associated with Christianity’s origins—simplicity, compassion, humility, and moral renewal—with the historical record of “organized” religion as an institution. The thrust is not necessarily anti-Christian but anti-institutional: once a faith becomes a bureaucracy allied to power, it can substitute dogma, coercion, and self-preservation for the founder’s aims. The word “probably” signals a rhetorical judgment rather than a documented claim, but it underscores a familiar modernist critique: that churches may impede the very moral progress they profess to champion, by policing belief, resisting reform, or sanctifying social hierarchies.
